Blaine Gardner 9009326ad7 Integration tests: use 'kubectl apply' vs create
Some integration tests fail due to resources from a previous integration
run not being cleaned up properly. Instead of using 'kubectl create' --
which fails with an error if the resource already exists -- to create
resources, use 'kubectl apply' -- which does not fail for pre-existing
resources. 'kubectl apply' will give a warning that it should be used to
apply changes to resources created with 'create' or 'apply', but there
is no error.
